Which Japanese foreign minister signed the 1945 surrender for the Emperor and Japanese government?

Mamoru Shigemitsu signed Japan's 1945 surrender for the Emperor and the Japanese government.

Shigemitsu was Japan's foreign minister when the Instrument of Surrender was signed aboard USS Missouri on September 2, 1945. The wording beside his signature stated that he signed by command and on behalf of the Emperor of Japan and the Japanese government.

He appeared in formal diplomatic dress and used a walking stick because he had lost a leg after an assassination attempt in 1932. His presence represented the civilian government, while the second Japanese signatory, General Yoshijiro Umezu, represented the Imperial General Headquarters and the armed forces.

Shigemitsu had also signed Japan's surrender to the Allies in a separate regional ceremony in 1945? No—the globally recognized ceremony in Tokyo Bay is the event associated with this signature. He should not be confused with Shigenori Togo, who was foreign minister earlier in August during the final surrender discussions.
